    conversion of 8V71 Turbo to NA

    Seems that you are wet stacking due to too much fuel at low load. The easiest/cheapest thing to do may be to put smaller injectors in. Detroit Diesel has a lot of info on sizes and ratings etc. You don't appear to be urgent so just a trial on one may work for you. Good luck and let us know...

    Twincharged setup, Supercharger THEN turbo?

    Apologies if I am restating anyone but I did not see it mentioned. Detroit Diesel 2-stroke engines, generally 6V92 and 8V92 had the setup you are discussing. The blower is in the original design anyway due to Positive Pressure Intake air needed for a Two stroke. Normally the turbocharger will...

    Cylinder Offset From Crank

    Our linkages book back in school had a whole chapter on this with software similation in the back. It is packed away from my last move but I'm sure you can search 4- bar linkages and come up with something. Maybe check martindales reference desk. Sorry I don't have a better answer. HTH

    Self Supercharging engine

    There has been rumor of people routing air through the bell housing to get some boost. The rumor said the Differential pressure was measurable. Put a couple holes into the top and route the positve pressure one to the air cleaner. A dividing plate between them may even help guide the air out...

    8-71 NA marine diesels

    pitchbait40, I cannot speak for the marine world but I do have that engine in my bus. The intake has a positive displacment supercharger/blower on the intake, it is a 2-stroke diesel. I have some info from people who put turbos on theirs and kept the boost low (6 psi & 12 psi). One had a...

    Turbo 1.8L Plenum vs. 1 into 4 performance concerns

    Tigretr, I'm no expert, but will the butterflys handle the 12 psi boost? Possibly so with individual Idle Speed Valves/Systems. My understanding is that the throttle body is normally upstream of the turbo. I would be interested in how this turns out. Keep us posted. Possibly you coud use a...

    Welding 17-4ph stainless steel

    CBF, It has been my experience that you would probably have to post weld machining to keep the bar perfectly strait. If you have the ability to machine it you may want to use a different means of fastening that may allow adjustability. Or possibly a low temp brazing to minimize the local...

    4 into 2 stroke using cam....would it run?

    I would be interested to see what you come up with, I have a Detroit Deisel 8V71 that is similar to what your considering. Two Stroke Deisel with cam/blower etc. the 92 Series (92 in^3/cyl) also have a turbo that feeds a blower. Hope this might help with your research. jomor

    Need help in re-designing rotating joint

    Just as thought. If the top square tube were a Hollow Split Round tube and a Male Round Peice(with lever arm attached) could be inserted, rotated, and clamped down. A pin and slot would allow for stops and keep it from falling out. The level adjustment/tierod could still be attached to the...

    Mazda rx8 wankel efficiency nearly there?

    If you dig around there is a video of the chainsaw somewhere. The last time I saw it it bogged down my computer. I would say the claims are theory, however it's a new theory to me and that's what I find most interesting(Kind of like the Coates Rotary Valve Heads of the early nineties, Wonder...

    Mazda rx8 wankel efficiency nearly there?

    If you like rotory engines, check this link out. He made a prototype with a zero-vibration chainsaw. http://quasiturbine.promci.qc.ca/QTIndex.html jomor
